Be it known that l, HARRY 'rnn KUILE, manufacturer, a subject of the Queen of the Netherlands, residing at Enschede, the Netherlands, have invented certain new and useful Improvements in Replenishing Mechanism for Multicolor Looms, of which the following is a specification.

slay which follows upon the changing of the position of the change-box. This is obtained by means of a very simplified mechanism.

In the accompanyin illustrate my invention,

Fig. 1 isa side elevation of the arrangement applied to a revolving circular changebOX loom, seen from the left hand side of the loom,

- Fig. 2 is a corresponding side elevation Wltl'l, an axis 31, and is divided by means seen from the right hand side of the loom, and i Fig. 3- is a front elevation of the same arrangement. 7

In the drawings, 1 is the revolving changeb oX, Each compartment of this change-box is provided with an electric feeler arrangement, ofthe type shown in American Patent No. 1,330,036, granted to me, the contact bow and contact spring 21 of which are shown in the accompanying drawings.

An electrical connection with a separate contact plate 22 is provided for every bow 2, At a determined point, the contact plates 22 connected with the change-box compartment, are contacting with a sliding contact spring 3 in such a way, that when such a contact plate 22 is in operation, contacts with the sliding contact spring 8 which is electrically connected with a contact-brush 23, the latter pressing against the periphery of a contact disc L. which revolves with the bottom shaft of the loom. The contact disc lis provided with a contact strip 25, which has a determined length and which co-operates with a second contact brush 24. At a certain moment which is determined by the length and by the position of the contact- I Specification of Letters Patent.

strip 25 and by the respective positions of the brushes 24:, 23, an electrical connection.

of the brushes 23 and 24 occurs. The contact brush 24 is electrically connected with a magnet coil 5, another conducting wire con necting the magnet coil 5 with one of the poles of a source of electric current, whilst the second pole of said source is electrically connected with the contact-strip 21 in each compartment of the change-box.

One of the outer ends of a pawl or catch- 6 is situated underneath themagnet coil, which pawl is rotatable around a bolt 26 the latter being fixed to a rod 9. When an electric current flows through the magnet coil, the latter attracts the outer end'of the pawl 6, which is situated underneath it,

whereby the other end of the pawl comes into such a position that it is able to engage a rocking hook 27 which forms one of. the outer ends of a bell crauk lever '7. "This bell-crank lever is rotatably mounted on a shaft 28, and its second arm is supported by an eccentricaldisc 8 which co-operates' with the bell crank lever insucha way, that the to and fro when latter is caused to rock the bottom shaft revolves.

[The cop-store 29 is hingedly connected of a partition wall 30 into two compartments, each containing cops of adetermined kind or color. The cop-store 29 is disposed above the path of the fixed shuttle-boxin such away, that the shuttle-box 34L is situated perpendicularly underneath the copstore at the moment when the slay has reached its utmost forward position.

A transferring hammer .10 which is rotatable around a fixed axis cooperates with the cop-store 29 and is hingedly connected to slayis beaten up, in which case the stud 32' pushes the arm 11 forward (to the left in Fig. 2), whereby the transferring hammer 1O eXpels a cop from the copstore and pushes it in the known way into the shuttle, at the moment the latter is present in the shuttlebox underneath the cop-store.

The following mechanism hasbeen. pro

s by means of a spring the ram 3 20,, the rod nected to the lever l8. l8, l6,,is mounted upon the shaft f aid lever l6. l8. is at itsother end The level hinsedly connectedwith a vertical rod l a lever rod 15..

The cop store 29 is hingedly connected to by incansot a rod 33. The lever l2 is suspended at its upper end in the same way apendulum. A hook l3 is hingedly connected to thelower end otthe suspended rod The hook l3 supported by the The rod 9 is provided with a stud 14,

the rod 15 is in its lower position.

The apparatus acts in the following way:

\Vhen the slay has reached its foremost position, and another color is wanted, the position of the change-box will be changed.

. Afterthis changinghas occurred, theslay 7 immediately goes backwards. i nent, (that is to say before the crankshaft of the loom has reached its.

I At this mothe crank ct lowest position) the teeler arrangement enters into active operation which is possible because at that moment the contactstrip 25 connects the contact brushes 23 2 nd. 2% electrically. If at the same time the cop, which is present in the respective changeboX compartment is sufliciently exhausted of yarn to enable an' electric current to flow from the contact-spring 21 through the shuttle, to the contact-bow 2, then the mag H net coil 5 'will be energized. This causes the pawl 6 to the magnet-coil.

it the same moment the hook 2? ismoving backwards to the right in Fig. 2, and engages the pawl or catch 6, so

that the latter is pushed backwards too. The

pawl 6 also pushes the rod 9, on which it is mounted, backwards. This causes the 11 to ascend, so that it comes in front of the stud 32, which is mounted on the slay. By the now occurring beating-up of the slay, the stud 32 presses the arm 11 forward, which occasions the transferring hammer to press a new cop mentis in position underneath the cop compartment in action. a The slay will then swing backwards, and the stud 32 leave the arm 11 free, so that the transferring hammer moves upwards.

store It the position otthe change-boxes has I been changed just beforethe pawl 6 has the rod 9.

underneath the transferringhammer, which is able to engagethe hook l3 when be attracted by into the shuttle, which at this Inoelectro-magnet to move said engaging means been attracted by the magnet coil, the cam disc 20*will have been rotated at the same time with the revolving change-boxand comes into a new position. If at this moment the rod enters into a recess of the cam disc 20, it consequently ascends to the depth of the recess, which causes the lever 18 to rise too. Consequently, the lever 16 descends, whereby also the rod 15 descends, so that the hook 13 engages the stud l l on backward movement oithe rod 9, (towards the right in Fig. 2,) the stud 14; moves the book 13 backwards, which also occasions the movement of lever 12 and rod 33 in a backward direce tion, so that the cop-store will be moved to the right in Fig. 2, till theopening in the bottom of the front section or compartment otsa'me is positioned perpendicularly underneath the outer end of the transferring hamnier'lO. In this 'way,the suitable compartment of the cop store can be brought sothat the desired cop-substitution takes place;

If on the ctmtrary, after thechanging of the position of the change-boxes, the rod 19 presses against a cam portion of the cam disc 20, the rod 19 wil be pulled downto' its lower position, whereby the rod l5'wil1 95 ascend to its upperpositionby means of the lovers l8 and 16; so thatthe book 13 also ascends, and thus remainsput of en- 5.1 gcment with the stud- 1 L onthe rod 9. ins causes the cop-store to remain in its normal-position, i. e. insuch a position that tl'reOPlliIlg at the bottom of its rear compartment behind the partition wall 30,16-

it evident that-the cam disc 20 may be substituted by any suitable means for actuating the rodlQ'of the leversysteni 19, 18,16,15. J

The cam disc 20 may for instance be fixed on a separate axis moved by means of a gear, which is operated by the change box. liaving fully described my invention, what I claim is 1. Automatic cops substituting mechanism comprising a cops store mounted for movement, a movable cops ejecting element, an operating rod, means for moving the cops .store including a member arranged for engagement w1th'and disengagement from said operating rod, means operated by a loom shaft for moving said operating rod, a member carried by said rod to engage and disengage said loom shaft operated means, an-
